Question for Elna owners
I have an Elna 7300 and it has been Wonderful. Then I had it maintenanced this last fall and the man has a great rep so this is not to put anything on him. Anyway since I've gotten it back I'll be sewing along and without warning the bobbin thread will start looping (stitches are big loops of thread). The other night sewing binding on a small table runner that should have taken me 20 minutes took over 4 hrs! The ripping out and crying took a lot of time plus trying different needles, rethreading, changing bobbin, using silicone circle under bobbin,(per Leah Day) taking it out every possible thing I could think of. I couldn't stop because it was a shower gift for the next day. I took it back to him once and of course it wouldn't do it then. I'm taking it to him again Friday. Anyone have any ideas or have you experienced this? I know he wants to solve this. Could it have anything to do with a factory setting? I average 5-10 hrs a week or so when I'm in sewing mode. But there are "no sewing" stretches too. It's not overworked. I bought it in Aug. of 2008. Any help is greatly appreciated.
